DUMPlNG-WAGON.

-3PEC'IIEICA'I'IOIl' forming part Of Letters Patent NO. 339,604, dated April 6, 1886.

Application filed August 18, 1885. Serial No. 174,162. (No model.)

To all whom it may concern.-

Be it known that I, ARTHUR G. VANKIRK, of Fort Recovery, in the county of Mercer,

in the State of Ohio, have invented a new and useful Improvement in VVagonDumps; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to improvements in dump-wagons, and is designed to produce a wagon of such construction as to conveniently dump contained material, and also be easily put together or taken apart.

I 5 In the drawings, Figure 1 represents a side elevation with the side-board of the body partially broken away, and Fig. 2 a similar view showing the mechanism during the operation of dumping.

The bottom of the body is formed of a series of lateral strips, 13, preferably thicker on one side than on the other. The thicker side is rabbeted, as shown at J, and each strip is pivoted near the said thicker side, the pivots 2 5 being shown at L. On the middle of the strips is raised an angle iron or frame, G, the angle being normally uppermost. A bar, D, is pivoted to the angles of the several frames C, one strip on each side of the frames, preferably, 0 and so connects the said strips thatthey move simultaneously and require but one point of impulse. A lever, E, is secured to the front strip B near its pivotal axis, and is pivotally connected to the front of the bars D. The lever carries a pivoted hook or catch, F, con nected to a hand-lever, G, by means of a rod,

H. The catch F normally engages over the front end, M, of the body, and is thereby retained.

WVhen it is desirable to dun1p,the catch is 0 disengaged from said front end. The weight of the material in the body will cause the strips to turn on their pivots and the lever fall to the rear, as shown in Fig. 2, thus releasing the contained material. The lever is then returned to the upright position, carrying the strips with it. The front end, M, and the rear end, N, have each eyes 0 on their ends, which eyes project through the sides A and receive pins P, which normally retain the sides and ends of the body together. The strips B are 5c pivoted to the sides A, and hence when the pins P are removed the entire body may be quickly taken apart. The strips D being arranged inside the body and elevated above the strips B, the said slats being rabbeted, and the lever being also within the body and secured to one of the slats, forming practically a continuation of one of the frames 0, cause the device to dump automatically when the catch F is disengaged from the end M. The 6( frames act as connections and braces for the strips B, thus performing a double function.

I claim- 1. A dumping mechanism consisting of a series of strips pivoted near one side, and also 6 there rabbeted, central bracing angle-frames on said strips, longitudinal bars connecting said frames at the angles, and a lever forming a continuation of one of the frames and carrying a catch or hook and handle connected to 7 the same, said lever having direct connection to said strips, substantially as and for the purpose specified.

2. The combination, with a body consisting of sides and ends having eyes projecting 7 through said sides and retained by pins, of a dumping mechanism consisting of a series of strips pivoted to said sides, connecting-strips, and a lever carried by one of the said strips, and provided with a catch or hook normally 8 engaging over one end of the body, substantially as and for the purpose specified.

ARTHUR O. VANKIRK.
